Do the dev's actually play this game?

[Aegrus]

Playing a tank is not the same as playing a healer. Playing Monk is not the same as playing Black Mage. I ask this because having a diverse point of view is important, especially when tanks and healers are often lynchpins of good groups.

If you want another specific example, the aforementioned Monk still has obvious issues with greased lightning, and prolonged phase shifts such as Living Liquid in A3. The phase transitions are so long, that it is quite easy to drop greased lightning, and they are designed around a ramp up to 3 stacks. Just the extra ~2sec of cast delay in it being applied at the start instead of the end of the animation alone makes a huge QoL difference in the class. This is something you wouldn't know unless you play or work with players who play monk often.

The bigger point of the OP was also that Dev experience is also not the end all, player feedback is really important.

Yes please, another comparison to WoW we all know how great this[that?] game turned out.

Other MMO's exist, and set standards and expectations, you would be a fool to not acknowledge what works well for others.
